There is a nagging sense of deja vu about the ground-breaking plans for Chris Evans to present the Friday edition of BBC1's teatime magazine show, The One Show, in addition to his excellent work on the BBC Radio 2 breakfast programme. Evans previously presented a Friday teatime show, Channel 4's TFI Friday, you may remember, while also presenting a national breakfast show on BBC Radio 1. The dual experience didn't end entirely happily. We can only hope that Evans – who is off air this week to "have a think" with his team, or a "regroup" as his newsreader Moira Stuart put it – doesn't ask Radio 2 controller Bob Shennan if he can work a four-day week.
